M136 AT4

The M136 AT4 is a portable one-shot, disposable, Anti-Tank Rocket Launcher built in Sweden by Saab Bofors Dynamics. In the US and NATO inventory, it replaced the M72 LAW. Saab has had considerable sales success with the AT4, making it one of the most common light anti-tank weapons in the world.

It is intended to give infantry units a means to destroy or disable armored vehicles and fortifications, although it is not generally sufficient to defeat a modern Main Battle Tank. The launcher and projectile are manufactured prepacked and issued as a single unit of ammunition, rather than as a weapon system, with the launcher discarded after a single use.

The M136 can be found during Crash and Grab in a small wooden barracks after the player gets through the village at the beginning, and is a common sight when players get to the many other settlements in the area. It is always seen on Haggard's back and he uses it against enemy vehicles and enemies behind light cover.

"Swedish made disposable 84mm anti-tank missile that is well balanced at neutralizing armor and fortified positions. It has been modified with a "guidance tracking system" that assists the warhead in homing in on the target engaged. It is not compatible with "tracer dart" aiming facilitators."

— In-game description

The M136 AT4 is a weapon featured in Battlefield: Bad Company 2. It is the third rocket launcher issued to the Engineer kit, requiring 13,700 points to unlock. Unlike the first game, the AT4 is not a fire and forget weapon and does not lock onto Tracer Darts.

It is a wire guided weapon much like a stationary anti-tank launcher. The projectile follows wherever the player looks, even if the weapon is scoped out. The player must maintain a line of sight on the target in order to hit it. It is also necessary to lead fast moving targets, as the red box must catch up with the main crosshairs.

This can be done by positioning the red box over the intended target. However, another way to use the weapon would be to focus on the projectile rather than the red box since the red box can be distracting.

The AT4 does 20 more damage to enemy armor than the RPG-7, and its guidance system makes it somewhat more efficient at destroying enemy armor and helicopters. However it does poorly against infantry compared to the Carl Gustav because the Gustav has the largest splash damage. However, players can easily guide the rockets in order to directly hit the enemy without compensating for rocket drop. This also allows for the player to lead the target much more easily and on the fly compared to firing the rocket at a pre-determined area in front of the moving enemy.

If a player knows how to use the AT4 well, it can be effective against fast moving vehicles such as the Patrol Boat Light or Quad Bike, whilst potentially freeing the sidearm slot for a pistol, rather than a Tracer Dart Gun.

The AT4 is the first anti-tank weapon wielded and is also carried by Christian Matkovic throughout the Singleplayer campaign.

Henry Blackburn uses it during the mission Operation Swordbreaker to kill a dug in enemy sniper in a hotel. It goes unused during the remainder of the singleplayer campaign, with the USMC anti-tank weapon of choice being the SMAW. It is not available for use in multiplayer.

It inflicts much greater damage than the other shoulder-fired rockets, and always inflicts at least critical damage (Mobility Hit) on the target regardless of where the rocket strikes. It can destroy any small ground transport or air vehicle in a single hit, including transport helicopters.

Its ironsights are zeroed at 50 meters, with the bottom of the reticle plate's semicircle at roughly 225 meters. Although very accurate, the reticle's design completely blocks vision of areas beneath the zero point, hindering long-range usability. Only one rocket is provided with each pickup. It has noticeable drop at range, roughly between that of the SMAW and RPG-7V2.

The "reload" animation for the AT4 depicts the launcher being discarded and another one being pulled from the player's back. In third person, the animation shows the player's character dropping the launcher on the ground where it disappears, and it then reappears on the player's shoulder as a new one is prepared.

While using a US Demolition kit, if the player swaps their kit with another that does not have the AT4, the launcher will still be present on the player's back. If a US Demolition actually has an AT4, the launcher on the character model's back will be removed by the character model when the player switches to it.

The AT4, like the RPG-7, can kill enemy soldiers instantly when used against them, however the AT4 and RPG-7 hardly do any splash damage when compared to the M2.

In multiplayer, USEngineers always have an AT4 on their back, regardless of what launcher they actually have, similar to how Russian Engineers always have an RPG-7 on their backs. Like in Bad Company, the launcher is taken off of the player's back when they switch to it.

In Battlefield: Bad Company 2, Haggard no longer carries his signature M136 AT4 like he does in Battlefield: Bad Company.

The projectile speed and splash damage of the AT4 was increased in a patch.

The AT4 is the only rocket launcher without rocket gravity drop, since it fires guided rockets.

In "Operation Swordbreaker", when the AT4 is passed over to Blackburn it says "Hold X to pickup RPG", a possible oversight between the level and scenario designers. Matkovic refers to it (generically) as an RPG.

After Matkovic passes the AT4 to Blackburn, it can still be seen on his back.

The AT4 is seen strapped to the back of the engineer kit in Battlelog.

Originally, the Supply Crate on the Test Range would resupply a Battle Pickup weapon with 99 rounds in reserve. When performed with the AT4, the launcher possessed no reloading animation, as it is intended to be discarded immediately after firing; instead, the weapon would simply reappear shortly after firing. This is no longer possible to observe, as the Supply Crate's ability to do this was later removed with a patch.
